Summary

Lago through 1.55.0 contains an authorization bypass in Invoices::Payments::StripeService (CWE-639). The invoice lookup is not scoped to the organization, so a user of one organization can mark another organization's invoice as paid. An authenticated user with low privileges who controls their organization's Stripe integration can use a signed payment event to unlock wallet top-ups or payment-gated subscriptions.
